Reach level 25 with each of the four original 
characters to unlock Falconess, Minotaur, Tigress, 
and Jackal. Load your level 25 character and start 
a new one through character management. Hold Turbo 
and you will notice your character has turned into 
its counterpart. For example, Barbarian becomes 
Minotaur and Wizard becomes Jackal. 
They can be selected with any color.
